About this network

Alibaba Cloud / Aliyun (ALIBABA-CN-NET) — the China-based network of Alibaba's cloud division, the largest cloud provider in China.

What it's used for

• Hosting customer workloads on Alibaba Cloud within China, plus Alibaba's own services (e.g. its e-commerce platforms).

Notable

• An IP here identifies Alibaba Cloud as the host; the workload is usually a customer's. Domestic-China traffic is subject to national filtering.
• Distinct from AS45102, which serves Alibaba Cloud's international regions.

Interesting

• Alibaba Cloud dominates the Chinese market much as AWS does globally, and underpins the huge traffic spikes of events like Singles' Day.
